Sound of Bluetooth headphones/speakers cuts or noise occurs

Various reasons can cause noise interference to the sound of Bluetooth headphones or speakers. Please check the following solutions for each cause:Alternatively, you can visit our Sony Headphones Troubleshooting Guide for other options.

Reasons

Workarounds

Case 1

When using the Bluetooth device close to Wi-Fi routers, personal computers, microwave ovens, refrigerators, etc. Wi-Fi routers, personal computers, microwave ovens, refrigerators, etc. are devices that emit radio waves. Bluetooth devices may be affected by these radio waves when using them in a location with a mixture of multiple radio waves.

Please use the Bluetooth device away from Wi-Fi routers, personal computers, microwave ovens, refrigerators, etc. in order to avoid radio wave interference.

If you use a headphone set with a noise canceling function, turn the noise canceling function off.

Case 2

When using the Bluetooth device in the pocket of the chest or pants, or a bag while listening to the audio. This is because the human body blocks the Bluetooth antenna of the Bluetooth device and creates an obstacle for Bluetooth transmission.

Move the Bluetooth device to a position where there is no obstacle, such as a human body, to Bluetooth communication when using the Bluetooth device in a pocket or a bag.

Case 3

When using the Bluetooth device closes to the other Bluetooth devices.Bluetooth devices may be affected by these radio waves when using them in a location with a mixture of multiple radio waves.

Turn off the Bluetooth function of the other Bluetooth devices.

Case 4

When using the device away from the player, such as in a different room. Bluetooth communication gradually becomes weaker the further away Bluetooth headphones/speakers are placed from a Bluetooth player.When using Bluetooth headphones/speakers and a Bluetooth player in different rooms with the doors closed, Bluetooth communication may be weak.

Keep the Bluetooth headphones/speakers as close to the Bluetooth player as possible.

Case 5

When playing music (audio data) via the Bluetooth device placed in a case. If a protective case uses metal objects or thick materials, Bluetooth communication is interfered by those objects/materials and the signal may be weak.

Remove the case of the Bluetooth player.

Case 6

When playing music (audio data) streamed via the Internet. Sound is affected by the communication condition of the Internet since music (audio data) that is streamed to a Bluetooth player is transferred to Bluetooth headphones/speakers. Furthermore, playing music (audio data) that has a large volume has more impact on sound.

Play downloaded audio contents, not stream via the Internet.

Case 7

When playing music with a large file size or High-Resolution audio format. The file size becomes large when music files are compatible with the High-Resolution audio format. Music files with a large size may affect Bluetooth communication.
